Abstract

This study aims to determine the distribution pattern and population density of Buchanania arborescens (Blume) Blume in Ultramafic Soil, Podi Village, Tojo District, Tojo Una-Una District, Central Sulawesi. Observations were made using the purposive sampling method by establishing five (5) transects 50x10 m in size which there were subplots with size 10x10 m to observe tree (DBH >10 cm), 5x5 m for the sapling and 2x2 m for seedling with a distance of 20 m between transects. The distribution pattern of Buchanania arborescens at the study site was determined by calculating the morbidity index with the results of calculations on seedling phase Id (0.04), sapling Id (0.05) and tree Id (-1.00). The highest density of Buchanania arborescens is in the seedling phase with a value of 200 individuals/Ha, the sapling phase is 176 individuals/Ha and the lowest value is in the tree phase with a total density of 40 individuals/Ha. The results showed that the distribution pattern of Buchanania arborescens for the seedling and sapling phases were clumped, while the tree phase was uniform. The density of Buchanania arborescens was rare density category.

Abstract

Soybeans, yardlong beans and peanuts are cultivated crops widely grown in the tropics at different altitudes. Differences in environmental factors between lowlands and highlands will affect plant growth and leaf anatomical structure. The study aimed to determine the growth and anatomical structure of the leaves of soybean, yardlong bean and peanut plants at different altitudes. The test plants were grown at two different altitudes. At an altitude of ± 20 masl, the test plants were placed in the greenhouse of the Biology Department of the Faculty of Mathematics and Natural Sciences, Tadulako University and at an altitude of ± 630 masl, the test plants were placed in Bahagia Village, Palolo District, Sigi Regency. The results showed that yardlong bean and peanut plants grown at an altitude of ± 630 masl had a lower stomatal density than those grown at ± 20 masl so the plant dry weight produced was also lower. Soybean plants have a larger stem diameter and plant dry weight at an altitude of ± 630 masl, these are due to the higher stomatal density and leaf thickness compared to those grown at an altitude of ± 20 masl.
